A MULTIPLEX HUMAN PLURIPOTENT STEM CELL PLATFORM DEFINES MOLECULAR AND FUNCTIONAL SUBTYPES OF AUTISM

ABSTRACT: We report a multiplex human pluripotent stem cell platform to investigate autism associated genetic variation during the development of the prefrontal cortex. This dataset represents the biological replicate datasets of our hPSC-derived prefrontal (PFC) and occipital (OCC) differentiation compared with neural stem cells (NSCs). We find that the top genes associated with PFC identity correlate well with in vivo PFC using the Allen Developmental Transcriptome data.

Dysregulation of the Wnt/β-catenin signaling pathway via Rnf146 upregulation in a VPA-induced mouse model of autism spectrum disorder

Project description:To investigate the function of RNF146 on gene expression and signaling pathways, we overexpressed RNF146 in mouse prefrontal cortex (PFC) using AAV and performed RNA-seq analysis. We found that genes in Wnt signaling pathway are differentially expressed in RNF146 expressed PFC compared to control.

Towards a human brain EV atlas: Characteristics of EVs from different brain regions, including small RNA and protein profiles

Project description:Brain derived EVs (bdEVs) from eight brain regions, including orbitofrontal gyrus(ORB), postcentral gyrus (POSTC), hippocampus (HIPPO), thalamus (THAL), occipital gyrus (OCC), medulla (MED), corpus callosum (CORP), and cerebellum (CBLM) were separated and characterized by small RNA sequencing. We aim to provide an atlas of bdEV molecular profiles with brain region specificity.

Allele-specific expression in a family quartet with autism reveals mono-to-biallelic switch and novel transcriptional processes

Project description:Autism spectrum disorder (ASD) is a highly prevalent neurodevelopmental disorder, and the exact causal mechanism is unknown. Dysregulated allele-specific expression (ASE) has been identified in persons with ASD; however, a comprehensive analysis of ASE has not been conducted in a family quartet with ASD. To fill this gap, we analyzed ASE using genomic DNA from parent and offspring and RNA from offspring’s postmortem prefrontal cortex (PFC); one of the two offspring had been diagnosed with ASD. DNA- and RNA-sequencing revealed distinct ASE patterns from both offspring PFC. However only the PFC of the offspring with ASD exhibited a mono-to-biallelic switch for LRP2BP and ZNF407. We also identified novel RNA-editing and monoallelically-expressed genes and miRNAs. Our results demonstrate the prevalence of ASE in human PFC and ASE abnormalities in the PFC of a person with ASD. Taken together, these findings may provide mechanistic insights into the pathogenesis of ASD.

Conserved expression of lincRNA during human and macaque prefrontal cortex development and maturation

Project description:78 tissue samples from prefrontal cortex (PFC) in human and macaque The data from human and macaque PFC samples with different ages were used to estimate gene expression changes, including both protein-coding genes and lincRNAs, in PFC along lifespan in the two species.

Encoding of Contextual Fear Memory Requires De Novo Proteins in the Prelimbic Cortex

Project description:Time dependent coordinated hippocampal-prefrontal cortical interactions are required for the long-term storage of memories. However, the role of prefrontal cortex (PFC) in encoding of long-term memories remains elusive. Here, we discover a critical role of PFC in the encoding of contextual memories in mice. We demonstrate that specific pools of mRNAs are translated in the PFC following one and six hours of behavioral training. Moreover, disruption of protein synthesis in the prelimbic region of PFC immediately after training inhibits encoding contextual fear memories, whereas disruption at six hours after training is ineffective. Thus, early protein synthesis in the PFC is necessary and critical for the encoding of contextual fear memories. These findings establish key role for the prelimbic cortex in encoding of contextual memories.

Amelioration of autism-like social deficits by targeting histone methyltransferases EHMT1/2 in Shank3-deficient mice

Project description:Many of the genes disrupted in autism are identified as histone-modifying enzymes and chromatin remodelers, most prominently those that mediate histone methylation/demethylation. However, the role of histone methylation enzymes in the pathophysiology and treatment of autism remains unknown. To address this, we used mouse models of haploinsufficiency of the Shank3 gene (a highly penetrant monogenic autism risk factor), which exhibits prominent autism-like social deficits. We found that histone methyltransferases EHMT1 and EHMT2, as well as histone lysine 9 dimethylation (specifically catalyzed by EHMT1/2), were selectively increased in the prefrontal cortex (PFC) of Shank3-deficient mice and autistic human postmortem brains. Treatment with the EHMT1/2 inhibitor UNC0642 or knockdown of EHMT1/2 in PFC induced a robust rescue of autism-like social deficits in Shank3-deficient mice, and restored NMDAR-mediated synaptic function. Activityregulated cytoskeleton-associated protein (Arc) was identified as one of the causal factors underlying the rescuing effects of UNC0642 on NMDAR function and social behaviors in Shank3-deficient mice. UNC0642 treatment also restored a large set of genes involved in neural signaling in PFC of Shank3-deficient mice. These results suggest that targeting histone methylation enzymes to adjust gene expression and ameliorate synaptic defects could be a potential therapeutic strategy for autism.

Microarray Analysis of the Developing Murine Prefrontal Cortex

Project description:Abnormal development of the prefrontal cortex (PFC) is associated with a number of neuropsychiatric disorders that have an onset in childhood or adolescence. Although the basic laminar structure of the PFC is established in utero, extensive remodeling continues into adolescence. To map the overall pattern of changes in cortical gene transcripts during post-natal development, we made serial measurements of mRNA levels in mouse PFC using oligonucleotide microarrays. We observed changes in mRNA transcripts consistent with known post-natal morphological and biochemical events. Overall, most transcripts that changed significantly showed a progressive decrease in abundance after birth, with the majority of change between post-natal weeks 2 and 4. Genes with cell proliferative, cytoskeletal, extracellular matrix, plasma membrane lipid / transport, protein folding, and regulatory functions had decreases in mRNA levels. Quantitative PCR verified the microarray results for six selected genes: DNA methyltransferase 3A (Dnmt3a), procollagen, type III, alpha 1 (Col3a1), solute carrier family 16 (monocarboxylic acid transporters), member 1 (Slc16a1), MARCKS-like 1 (Marcksl1), nidogen 1 (Nid1) and 3-hydroxybutyrate dehydrogenase (heart, mitochondrial) (Bdh). Keywords: time course, development, mRNA expression Single-channel affymetrix arrays were used to profile mRNA expression in the prefrontal cortex (PFC) of male mice at different time-points after birth (post-natal). Each array is an independent animal.
